Maskim, in Babylonian occult tradition, was the seven evil spirits
associated with the seven planets. They were thought to rise in the west
and set in the east, just opposite of the solar path; and the brought ever
illness, calamity, and destruction to humanity. Impressive rituals to ward
off the influence of the Maskim still survive in Mesopotamian clay records.
